After a while, you begin to wonder where all of these GB500s have been hiding. With only 3400 miles and no blemishes you can see in the photos, this one looks like it just arrived from 1989.
The bike has been ridden, at least a little, but somehow, in those miles, no chips or scrapes or rubs appeared. There aren't even any scratches around the ignition where a key might have dragged or bumped the metal.
Someday we'll find the wormhole where time travelers are returning to an earlier year to snatch these pristine examples of vintage motorcycles and bring them up to the present, but until we do, we'll just have to look at bikes like this and accept them for what they are, perfectly clean used bikes with nary a scratch. This one is for sale on eBay, but the seller, who states it's the 232nd one ever made, is asking a lot, $10,500, which is definitely more than these usually sell for, though you can make an offer at a lower price, which is what I would recommend.
